Standard of care for rehabilitation in critical illness

BACKGROUND: Rehabilitation is recognised as a cornerstone of intensive care, essential for optimising functional recovery and reducing long-term disability. Contemporary ICU populations, characterised by advanced age, multimorbidity, and prolonged stays, are at heightened risk of muscle wasting, immobility, frailty, cognitive decline, and functional dependence. Mitigation of these sequelae requires careful interprofessional collaboration for person-centred rehabilitation across the care continuum. CONTENT: This review synthesises evidence from randomised controlled trials, meta-analyses, and clinical practice guidelines on rehabilitation during and after intensive care. Best practice within the ICU begins with early awakening and mobilisation with evidence demonstrating that physical rehabilitation is safe, with low adverse-event rates. Furthermore, multiprofessional strategies that span across ICU, ward, and community are required to address complex problems including physical, cognitive, and psychological sequelae of critical illness. FUTURE DIRECTIONS: Research priorities include detailed reporting of intervention dose (timing, intensity, duration) for both usual care and rehabilitation provided within clinical trials, and development of intervention implementation strategies that enhance uptake and fidelity in routine practice. CONCLUSION: Rehabilitation is integral to contemporary ICU care, spanning the trajectory of recovery into the community. Within the ICU, it requires interprofessional, experienced healthcare personnel to assess clinical status for safe rehabilitation and to identify an individual's anticipated recovery trajectory. Standardised intervention reporting and implementation-focussed research are essential to advance evidence and improve outcomes for critically ill patients.
